TAPPING DEVICE FOR CASKS.

SPECIFICATION forming part of Letters Patent No. 635,641, dated October24, 1899.

Application filed February 4, 1898. Serial No. 669,106. (N0 model.)

To all whom it may concern.-

Be it known that I, ANTON BECKER, master brewer, of 23 Rohrestrasse,Cologne-on-the- Rhine, in the German Empire, have invented an ImprovedTapping Device for Casks, of which the following is a specification,reference being had therein to the accompanying,

drawings.

The present invention relates to a device for drawing liquid from casks,particularly from casks which are emptied under pressure.

The said device consists of three partsa tap, a hollow plug entering thebarrel, and a casing screwed into the cask and into which the tap andplug are screwed; and my invention is characterized, essentially, by thefact that the casing or sleeve screwed inside the cask acts by means ofa rubber ring fixed in the casing to makeaperfectly-tight joint with theplug through which the liquid is to be drawn off. Furthermore, the tapcarries at its end an oval extension, which is inserted into theenlarged aperture (formed as an oval to correspond with the extension)of the plug, so that by screwing the tap into the casing the plug isscrewed up, whereby a connection is effected between the interior of thecask and the tap. a

In the accompanying drawings, which illustrate one form my invention mayassume, Figure 1 is a view showing the casing and the plug inlongitudinal section and the tap in elevation, while Fig. 2 is across-sectional View of the casing and plug on the line A B of Fig. 1.

The casing or sleeve a is screwed fast in a cask-stave F. In this casinga is inserted the plug b, which can be partially screwed into a andadjusted by means of its screw-thread on 19 It consists of a narrowtubular part b, which is closed at its end and terminates advantageouslyin a point, and of an enlarged rear part 11 which is externallyscrew-threaded. The narrow tubular part b is formed with any desirednumber of apertures 0, according to requirement, four being shown in thepresent case. The liquid is able to flow through the apertures 0 intothe interior of the plugb when the plug is sufficientlyscrewed up intothe casing a. The part bof the plug is guided in and makes a tighterjoint with means of the screw-threaded screw-ringf,

which screws into the tapped hole in the sleeve to and screws up tightlyagainst the rubber gasket, so as to compress same and cause it to form atight joint with the plug when the latter is inserted. For this purposethe screwringfmay be adapted to be engaged by a suitable key of anykind, so that it may be screwed up into place, the said ring having, forexample, holes which receive pins on the end of a key.

The screwing of the plug 1) into the casing a is effected by means ofthe cook or tap it, which is provided for this purpose with an ovalextension 2',which is inserted into a similarly-shaped oval aperture Itof the enlarged part b of the plug 1). Connected to the ex tension 2' ofthe cook or tap it is a part m, which is provided with screw-threadscorresponding to the internal screw-threads of the casing to, thusallowing the cook or tap h being also screwed into the casing a. It nowthe extensioni of the cock h be inserted into the plug 19 and then bescrewed into the cas ing a, the plug 1) will also be screwed up and theapertures 0 will be brought into communication with the interior of thecask, so that the liquid can then flow direct from the inte rior of the,cask through the plug 1) into the cook it. The cock his of coursealways closed while it is being inserted, so that no liquid can flowout. The two handles 0 on the cock serve to facilitate the screwing ofthe said cock into the sleeve or casing a. A rubber disk or washer p isprovided to make a tight joint between the cock and the casing a.

WVhat 1 claim, and desire to secure by Let ters Patent of the UnitedStates, is

A hermetically closing and drawing-off device for casks, consisting of,in combination, a casing to screwed fast in the cask having a tappedhole and a shoulder g, a rubber ring 61 inside the said casing, ascrew-ring screwed into said tapped hole and pressing ring 61 againstshoulder g, a plug Z2 with lateral holes In witness whereof I hereuntoset my hand a and adapted to screw up in the casing a, in presence oftwo witnesses.

making a tight joint with the said casing and v T 3 a cook it adapted toengage with and screw TON LECKER" up the plug 1) to allow of tapping thecask in Witnesses:

a perfectly tight jointed manner without K. MINNsKI, Waste of liquid,substantially as described. I KARL HARTMANN.
